FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The PDU13F-series device is a 3-bit digitally programmable delay line.
The delay, TD_A, from the input pin (IN) to the output pins (OUT, OUT/)
depends on the address code (A2-A0) according to the following formula:
IN Delay Line Input
OUT Non-inverted Output
OUT/ Inverted Output
TD_A = TD₀ + T_INC * A
A2 Address Bit 2
A1 Address Bit 1
where A is the address code, T_INC is the incremental delay of the device,
and TD₀ is the inherent delay of the device. The incremental delay is
specified by the dash number of the device and can range from 0.5ns
through 50ns, inclusively. The enable pin (EN/) is held LOW during

normal operation. When this signal is brought HIGH, OUT and OUT/ are forced into LOW and HIGH
states, respectively. The address is not latched and must remain asserted during normal operation.
SERIES SPECIFICATIONS
• Total programmed delay tolerance: 5% or 1ns,
whichever is greater
• Inherent delay (TD₀): 6ns typical (OUT)
5.5ns typical (OUT/)
• Setup time and propagation delay:
Address to input setup (T_AIS): 6ns
Disable to output delay (T_DISO): 6ns typ. (OUT)
• Operating temperature: 0° to 70° C
• Temperature coefficient: 100PPM/°C (excludes TD₀)
• Supply voltage V_CC: 5VDC ± 5%
• Supply current: I_CCH = 45ma
I_CCL = 20ma
• Minimum pulse width: 20% of total delay
